I have several tools from my father's collection. Some are near daily users and some are lookers only because they were his. Here is something from his collection that I just don't know what it is or what to do with it. I can't fully read the inscription but it does show up better when it is wet (in the photos). It is hard but the surface is almost soapstone like. It does not indent with a fingernail nor can I scratch it with a fingernail. It is really dark red-browinish color. Most of the wear seems to be storage related. Is it some sort of strop or finish stone? Paperweight? Any ideas?
